Tech Mahindra Interview Questions For Freshers

1. Define function overloading in C++.

Function overloading is one of the critical features of Object-Oriented programming. It allows two or more functions that have different logic to have a common name. In other words, function overloading creates two or more functions with different arguments but with a common name. This is because different data types will have a different number of arguments. As a whole, function loading tends functions to perform various operations.

2. What are inline functions in C++?

Inline functions, in their most basic form, are functions with short definitions. We place a keyword inline before a function name. We use inline functions to speed up the execution time of a program. We usually use inline functions for small computations but not for large computations.

3. What do you understand about tokens in the ‘C’ language?

Compilers use tokens to compile programs. They break codes into several blocks known as tokens and then compile the codes. Tokens are nothing but the building blocks used to construct a C program.

Know that there are six types of tokens in C, such as identifiers, constants, keywords, special characters, operators, and strings.

4. What do you mean by “transparency” in DDBMS, and mention its types?

DDBMS is the short form of Distributed DBMS, which refers to multiple systems. Transparency in DDBMS deals with hiding the implementation details of data from users. It means users can access data from databases, but they don’t know how the data is organized in the databases.

There are four types of transparency in DDBMS. They are distribution transparency, performance transparency, transaction transparency, and DBMS transparency.

5. Explain ClassLoader in Java.

The ClassLoader is nothing but a part of the Java Runtime Environment (JRE). It loads Java classes into Java Virtual Machine (JVM) dynamically. And it loads classes during the run time. The class loader works based on visibility, delegation, and uniqueness. Know that there are three class loaders: the extension class loader, bootstrap class loader, and system class loader.

6. Describe: Microkernel in Operating System?

A microkernel is the type of kernel used to manage the entire system's resources. A microkernel is responsible for the scheduling of the CPU, inter-process communication, and memory management. When we start a computer, the microkernel is the first program executed after the bootloader. Usually, a microkernel is located inside a kernel.

Know that microkernels are modular. We can change, swap, and reload modules without affecting the kernel.

7. What do you mean by a process, and name its different types in the context of computers?

A process is nothing but a program under execution. A process usually undergoes various states throughout its life cycle. The states are new state, running state, ready state, wait state, suspend ready, terminated state, suspend wait, and suspend blocked. Further, the Process Control Block (PCB) stores process states.

8. What do you understand by double-linked list programs?

A double-linked list allows traversing through the list forward and backward. Every double-linked list consists of many nodes. The nodes are connected sequentially, forming a chain, and are used to store data.

Each node in a double-linked list has two pointers known as "previous" and "next." The 'previous' pointer points out the previous node in the node chain or list. Similarly, the 'next pointer' points out the next node in the list. The head is the starting node of a double-linked list. It is essential to note that the 'previous' pointer in the head node is always NULL.

9. Briefly describe macros in the ‘C’ language.

A macro is a name given to an expression or a value. The syntax of a macro has three components: a macro name, a preprocessor directive, and a macro value. Macros don't indicate any memory location. Also, there can't be a single name for two macros.

10. Define segmentation and fragmentation in memory management.

Segmentation is the process of dividing storage spaces into many segments. There is no rule that the lengths of segments must be the same. In other words, segments will be of variable length. Note that a segment can be a stack, function, table, etc.

Fragmentation represents a state that indicates the inefficient use of storage spaces. It reduces both the performance as well as the capacity of systems. There are two types of fragmentation: internal and external fragmentation.

11. Describe the "finalize" () method in Java.

It is a method of the object class that supports garbage collectors to delete objects. This method is called default and performs a clean-up activity before deleting objects. In other words, it releases all the resources an object uses before the garbage collector deletes it. Moreover, this method helps the JVM to optimize storage spaces.

12. Compare: Paging and Swapping in Operating Systems.

13. What do you mean by "Servlet Collaboration"?

15. Can we define the main () method as private in Java?

No. If we define a main () method private in Java, the JVM won't access the method. Note that Java will compile successfully but throw errors during the runtime.

16. Differentiate: Functions and Macros

Functions	Macros
There is no preprocessing. Functions are compiled directly.	Macros are preprocessed before compiling.
No change in code length	It increases code lengths.
Functions won’t create any side effects.	It could create side effects.
It slows down the speed of execution.	It increases the speed of execution.
It checks for compile-time errors.	It doesn’t track compile-time errors.

Using Pragma pack:

Using Attribute:
